SHADEJ-IOLDER FOR INCANDESCEN'I ELECTRIC AND OTHER LAMPS.

Specification of Letters Patent.

Patented Feb. 18, 1913.

Application filed September 25, 1911. Serial No. 651,209.

To all whom it may concern Be it known that I, DANIEL GREEN SAUNDERS, Jr., a citizen of the United States, residing at Kansas City, count of Jackson, and State of Missouri, have invented certain new and useful Improvements in Shade- Holders for Incandescent Electric and other Lanps, of which the following is a specification.

This invention relates to shade-holders; and is particularly adapted to incandescent electric lamps and adapted for use in lieu of the brackets with rigid shade holding rings and set screws used heretofore.

It is the object of my invention to provide an attachment for the purpose above stated which shall be simple, cheaply manufactured and easily attached to and detachable from the socket or shade. I

Heretofore shade-holders for incainlescent electric lamps have utilized a number oi. set screws for securing the shade to the holder but such set screws have to be inanipulatwl individually and are also tedious and hard to manipulate, and furthermore they are often the cause of breaking or cracking the shade when set or screwed in too tightly.

It is the object of this invention to obviate the above mentioned objections and to produce an article which is convenient and easy to handle in eonniaetion with a socket and shade and also strong and rigiil in construction and cheap to manu't'actiiire.

My invention involves all the uses of this device but will describe it mainly in connection with. incandescent electric lamp sockets.

Figure 1 is a pers 'iecth'e view of the shade-holder in an inverted position. Fig. E2 is a top plan view of the same holder showing also in dotted lines the position of the tree arms of the rings when Fig. 3 is a plan view of a modification, and Fig. l is a transverse vertical section along line ;c;r of Fig. Fig. 5 is a plan view of a inm'lilication.

My improved device as herein shown comprises an. open adji'istable shade-hidding ring 1, a smaller. open, and adjlttable clamping ring 2 located within the ring 1., and flat connecting arms 3 and l. This device inits preferred form is formed or struck out of a'single piece of wrought metal thus making it economical to manufacture and with no loose or riveted parts to become deranged. In order to form the rings 1 and 2 so as to be open and adjustable, these rings are cut open or apart on one side at the junction of each ring with the connecting arm 3, and the metal is drawn downward to form lugs 01' shoulders 5 and (3 on the ring 2 and the lugs or shoulders 7 and 8 of the ring 1 (see Fig. 2). When these rings are thus fornred the drawn and cut out portions leave openings or spaces a and b in the rings 1 and 2 respectively. (Fig. 2), the dotted lines indicating the free ends of the rings in open position as when they are formed or struck out. These spaces a and 7) represent the adjustments allowed by spreading or closing the rings.

In forming the lug o a fiat angular boss 9 is formed integral therewith and with the adjacent ring so as to make the lug (3 more rigid in its radial position. For a like purpose a boss 10 is formed integral with the lug 8 and its adjacent ring.

Any desired number of connecting arms might be used for cimnimting the two rings together but it is deemed most practical to use but two as herein shown and to have them so arranged that the free end portion of each ring is longer than the remaining portion for the purpose of giving as much resilience as possible.

It will be readily seen that by spreading the free end portion oi" the ring 2 and thus enlarging said ring it may be slipped over a. socket and then clamped around same as desired. In this in'iproved device an ordinary screw passed through an enlarged hole (not threaded) in the lug 6 and thence screwed into a threaded hole in the lug 5 could be utilized to bind the clamping ring securely around the socket. much the same as is used in the ordinary shade-holder in cononon use. However. more convenientmeans might be used for this purpose as is herein shown. in which a compression coil spring 12 through which a binding screw 11 is passed, rests between the lug (3 and the head 13 0f the screw 11. \Vhen the ring 2 is placed around a socket, the coil spring l2 expands back to its normal position and forces the lug (3 on the tree '2 into contact with or toward the lug 5 and thus eonnn'esses the ring 2 around the socket. or the screw used in connection with the coil spring could be used to clamp the ring 2 around the socket.

Either the ordinary binding screw' end. of the ring t ha "ihering 1 is provided with inwardly exended ears letformed integral with the ing 1. These ears 14 are the means of sethe shade to the holder and they are dapted to be set into the groove on the o de the purpose of support. In placthe shade in position in the holder free end of the ring-l is spread open thus enlarging the ring 1 as shown by dotted lines Fig. 2 and the shade is then placed so that the ears 14- set within the grooveon the shade and the ring 1 is then closed and so heid by suitable means, as, by a binding screw 15 passed through an enlarged hole 18 (Fig. 4) (not threaded) in the lug 8 thence screwed into a threaded hole 1'? in the lug 7. As a convenience I have hereinwprosided a compression coil spring;

18 to be used with the binding screw 15 so as to'ireep the ring 1 normally in a closed position at all times, except, when pressure the purpose of spreading the ring 1 and either releasing the shade held thereby, or inserting the shade in the holder.

The great convenience and advantage of a shade-holder as herein described is evident, as, a shade can be attached to or de-' cracking the shade because of the'resilience in the ring 1.

' Fig. 3 shows a modified form of constructing this device by using several. parts and riveting the'same together.- The shade holding-ring 19 is made of one piece'of metal cut open at one side and there having radially extended lugs 20 and 21. "The binding screw 22 with or without a coil sprin is used for holding the ring 19 in'a close position in alike manner as described in connect-ion with Figs. 1 and 2. The clamp ing ring comprises two semicircular portions and 2A with radial extensions 25 and 26; riveted together at 27. The/extension 25 is secured or riveted by the rivet 34:

to the ear 28 carried by the ring 19. The opposite radial extension .29 of the portion .23 is riveted bythe rivet 35 to the car 31 carried b the rin The portion 2 a applied to compress the spring 18 for {Even if the coil.

carries a ra dierl -eigtension 32. r"; binding screw 33 eiiil'rerno; or. without the coil spring 30 is used, to bind the lugs or extensions'29 52 in a manner similar to that described in connection with Figs. 1. and 2. f

Fig. 5 shows a modified'form of this device adaptable for use on gas brackets. In this modifiediform the ring 2 is .not'open or adjustable but is. adapted to be fitted or secured around the gas tube in anysu'itable manner. The open adjustable shade holding ring 1 with the integrally formed ears I4 may be constructed similar to that-described in Figs. 1 and 2. Theconnecting arms; and 4 connect the two rings. In this structure, the device can be formed or struck out of a single piece of sheet or wrought metal. r I

I wish it understood that I'am not limited tothe precise detail constructions herein set forth,-inasmuch as many changes inform,

proportion and arrangement of -parts may 'be resorted to within the'spirit and scope f of my invention.

What I claim as my invention and desire to .secure by Letters Patent of the United States, is

1. In a-shade holder, an open adjustable shade'holding ring, lugs carried by said ring at its open side, spring pressed means of binding orretaining these lugs together so as to retain this ring in aclosed position independent of" adjustments in the clamp-- ing. ring; in combination with an adjust able clamping ring. v

2. In a shad holder, an open adjustable shade holding i'ing, lugs carriedby said of binding or retaining these lugs together so as to retain this ring in a closed positionindependent of adjustments in the clamping ring, an open adjustable clampingv ring,.lugs carried by saidfclamping rin means of binding or retaining these '11: together so as to retain the clamping rii in a closed position independent of adjust-- 'ments in the shade holding ring, and con necting arms connecting the two rings.

3. In a shade holder,;an open adjustable ring, lugs carried: by. said ring at its open side, a headed member secured to'one of said lugs add passing loosely through the other lug, coil. spring mounted. on th" headed member and. adapted for pressing the lugs. together.
